lthe pipe extending into the reservoir is of considerable length andheats up. the water in the reservoir and also the water in theconnecting passage to the diaphragm chamber of the governor valve. In mydevice this heating efect is greatly lessened owing to the short lengthof the tube c within the reservoir Z) and the globular formof thelatter, which. causes the bulk of'the water to be remote from the tube.

During operation of the device, it is understood that the vapor risingfrom volatile liquid in chamber a, responsive to action of Vsteam inchamber a', rises vthrough tube c to the space a-bove the fluid column`in the reservoir b and the tube d, and actuates this column in theWell-known manner.

I claim 1. In a feed water regulator of the char actcr described, thecombination cfa chamber for containing volatile liquid, a reservoiradapted tocontain a liquid column, a conducting means interposed betweensaid reservoir and the top of said chamber and having a threadedextension at the* end communicating'with said chamber, means fordelivering the fluid adjacent the bottom wall of said cl'iamber, and atubular sleeve internally threaded complementary to the said threadedextension. of said 'conducting means and movable toward or from the saidwall of said chamber to which the fluid is delivered, upon said threadedextension, substantially as and for the purpose set forth.

2. In a feed water regulator of the chap acter described, thecombination of a chamber for containing volatile liquid, a'reservoiradapted to contain a liquid column, a conducting means interposedbetween said reservoir and the top of said chamber and having a threadedextension at the end communicating with said chamber and eX- tendingbelow the uppermost cavity of said chamber, for delivering Huid adjacentthe bottom wall of said chamber, and a sleeve internally threadedcomplementary to the said threaded extension of said conducting meansand movable thereupon toward n,or from the said wall of said chamber towhlch the fluid is delivered, substantially as and for the purpose setforth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses this 12th day of December, 1910.
